Before we'd get things like this:
Input: $(foo bar)
Output: $(foo )
Input: $(($(foo bar) + 1))
Output: $(($(foo ) + 1))
Now we get things like this:
Input: $(foo bar)
Output: $(foo bar )
Input: $(($(foo bar) + 1))
Output: $(($(foo bar ) + 1))

Split out and rename functions and variables where appropriate.
Also add license headers. (The old scripts under parsing/ can be used
under the same license.)
